In the past Kolty has hosted a number of simultaneous exhibitions where a very strong player takes on like 20 or more opponents from the club. The games are OTB but some players will do simul’s. blindfolded without sight of any boards!
Below is a list of some players who have visited Kolty and given a simul. The list is ordered by title and alphabetically, not by year or results of the event.
Note the above picture is not of Kolty. It is of 8 year old Samuel Reshevsky, a chess prodigy, giving a simul. In 1920. For more information see Samuel Reshevsky - Wikipedia.
